Nicholas F. LaRusso,Russell H. Wiesner,Jurgen Ludwig,Robert L. MacCarty,Sandra J. Beaver,Alan R. Zinsmeister +5 more
TL;DR: It is concluded that the use of penicillamine in primary sclerosing cholangitis is not associated with a beneficial effect on disease progression or survival, and has considerable toxicity.
Journal ArticleDOI
Diurnal variation of serum iron, iron-binding capacity, transferrin saturation, and ferritin levels.
TL;DR: It is concluded that the practice of restricting iron specimen collections to a specific time of day does not improve the reliability of the test result.
Journal ArticleDOI
Evaluation of serologic disease markers in a population-based cohort of patients with ulcerative colitis and Crohn's disease
William J. Sandborn,Edward V. Loftus,Jean-Frederic Colombel,Kenneth A. Fleming,Frank Seibold,Henry A. Homburger,Boualem Sendid,Roger W. Chapman,William J. Tremaine,Debra K. Kaul,Jeannie S. Wallace,William S. Harmsen,Alan R. Zinsmeister,Stephan R. Targan +13 more
TL;DR: In patients with IBD, the sensitivity of ANCA varied widely in different laboratories, whereas the prevalence of ASCA was similar, and the positive predictive values of the ANCA assay combined with the ASCA assay for ulcerative colitis and Crohn's disease are high enough to be clinically useful.
Journal ArticleDOI
Reproducibility and simplification of 13C-octanoic acid breath test for gastric emptying of solids.
Myung-Gyu Choi,Michael Camilleri,Duane Burton,Alan R. Zinsmeister,Lee A. Forstrom,K. Sreekumaran Nair +5 more
TL;DR: The 13C-octanoic acid breath test for gastric emptying of solids is as reproducible as scintigraphy, but the sampling period should be extended to 6 h after dosing.
Journal ArticleDOI
Sex differences in evaluation and outcome of unstable angina.
Véronique L. Roger,Michael E. Farkouh,Susan A. Weston,Guy S. Reeder,Steven J. Jacobsen,Alan R. Zinsmeister,Barbara P. Yawn,Stephen L. Kopecky,Sherine E. Gabriel +8 more
TL;DR: The authors' population-based data indicate that after an ED visit for symptoms of unstable angina, the use of cardiac procedures was lower in women, but after taking into account baseline characteristics, men experienced worse outcomes.
